Heated seat element replacement

[AndyP]

I've not used these myself but I'd be cautious about condemming them if you haven't fitted them as they won't appear to get warm if you just turn them on in free space.
Put them between blankets or duvet and see if they get warm then.

Check that they consume the 5 amps they say they do. If they do that's 70 watts which is more than enough to warm even the coldest bum

That's exactley what I did, they were hooked up to a battery which was in turn connected to a 20A charger to ensure a consistant supply. I them put a towel either side of the element and sat on them! It took a good 5mins before I could even tell they were working, and even then I really had to concentrate. I did hook up a multimeter to check current draw but I can't remember what it was, not 5A though.

Cheap Chinese c**p, avoid.
